I normally hate the editing of movies for TV. I prefer they either bleep the vulgarity, instead of replacing dialogue.
I saw The Usual Suspects on USA replace "Give me the keys you **** sucker" with "Give me the keys you fairy godmother" and I couldn't take the movie seriously anymore. Once I saw The Big Lebowski where "This is what happens when you **** a guy in the ***" became "This is what happens when you make a friend in the Alps". Again, it totally takes you out of the movie.
The edit for Snakes on a Plane is however, to quote Dennis "fifteen gallons of awesome".
